Steel 55Cr3 vs 60CrMo3-1

Steel · grade comparison

Steel 55Cr3 and 60CrMo3-1 are both steel grades. 60CrMo3-1 is the stronger of the two: yield strength 1,520 MPa (220 ksi) against 480 MPa (69.6 ksi) for 55Cr3, about 3.2 times as much; tensile strength follows at 1,750 MPa (254 ksi) vs 800 MPa (116 ksi). In exchange, 55Cr3 is the more ductile: elongation 16% versus 7% for 60CrMo3-1, and 60CrMo3-1 is harder (480 HB vs 225 HB). 55Cr3 runs hotter in service (400°C vs 280°C continuous). On the shop floor, 55Cr3 machines more easily (fair vs not recommended), 55Cr3 welds better (poor vs not recommended), and 60CrMo3-1 sits in a lower cost tier (budget, $) than 55Cr3 (standard, $$).

55Cr3Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

60CrMo3-1Choose it when strength drives the design, or when cost is the deciding factor.

55Cr3 vs 60CrMo3-1 — frequently asked

Is 60CrMo3-1 stronger than 55Cr3?

Yes. 60CrMo3-1 has a typical yield strength of 1,520 MPa (220 ksi) against 480 MPa (69.6 ksi) for 55Cr3 — about 3.2 times as much. Tensile strength is 1,750 MPa (254 ksi) vs 800 MPa (116 ksi).

Which is cheaper, 55Cr3 or 60CrMo3-1?

60CrMo3-1 is the lower-cost material: it sits in the budget tier ($) while 55Cr3 is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, 55Cr3 or 60CrMo3-1?

55Cr3. Its machinability rates fair (50/100) against not recommended (10/100) for 60CrMo3-1; for welding the order is 55Cr3 first (poor, 25/100) then 60CrMo3-1 (not recommended, 10/100).
